摘要:
The invention relates to compounds made of (cyclo)aliphatic diisocyanates, produced according to a multi-stage method (phosgene-free production), which comprises the conversion of (cyclo)aliphatic diamines into the corresponding (cyclo)alkylene biscarbamates and the thermal cleavage of the latter into the (cyclo)alkylene diisocyanates and alcohol (urea route), and aromatic acid halides, and to the use thereof.
摘要:
A composite is produced by I. producing a reactive composition containing A) at least one organic diisocyanate and/or polyisocyanate; B) at least one compound having at least one functional group reactive toward NCO groups, wherein the ratio of NCO groups of A) and the functional groups of B) varies from 1:2 to 2:1; C) a catalyst mixture containing C1) at least one titanium compound and C2) at least one bismuth compound in a C1:C2 ratio of 100:1 to 1:100; and D) optionally, an additive; wherein the amounts of A)-D) add up to 100% by weight, II. directly impregnating a fibrous carrier with the composition from I., to obtain an impregnated fibrous carrier, III. shaping the impregnated fibrous carrier to give a molding, and IV. curing the reactive composition I.
摘要:
The invention relates to NCO-functional prepolymers prepared from dicyclohexylmethane diisocyanate (H12MDI hereinafter) and polyether polyols, with a reduced tendency to crystallization, a fraction of the H12MDI being blended with further monomeric isophorone diisocyanate (IPDI hereinafter), so making it possible to reduce or prevent entirely the tendency to crystallization, and also to the preparation and use.
摘要:
The invention relates to specific, hydroxyl-terminated polyurethane compounds containing uretdione groups and intended for use in the plastics sector.
摘要:
The invention relates to an apparatus for extracorporeal blood treatment having a dialyzer which is divided into a first and a second chamber 29, 30 by means of a semipermeable membrane wherein the first chamber 29 is arranged in a dialysate path and the second chamber 30 can be connected to a patient's blood circulation by means of a blood supply line 32 and a blood discharge line 31, an inlet 20 for fresh dialysate, an outlet 36 for spent dialysate, a measuring device 37, wherein the measuring device 37 has at least one radiation source 1 for substantially monochromatic electromagnetic radiation. Thereby the measuring device 37 for determination of a luminescence of the spent dialysate flowing through the outlet 36 has at least one detector system (5) for detecting the intensity of the electromagnetic radiation generated by luminescence.
摘要:
A substrate having at least four reference patterns at respective nominal positions on a surface is provided. Using a scanning electron microscope and positioning the wafer stage at respective nominal positions of each reference pattern, each reference pattern is scanned. After determining at least a first and a second intensity profile for each pattern, a reference position offset from each nominal position is calculated. The reference position offsets are used to determine a positioning error of the scanning electron microscope.
